This study investigates the effects of varying temperatures on co-pyrolysis wood sawdust (WS) and waste tires (WT) within a stainless steel fixed-bed reactor under nitrogen atmosphere. The experiments were conducted at three different temperatures: 400 °C, 500 600 focusing thermal behavior resultant product yields. At WS produced highest oil yield (63.6 wt%), suggesting tendency to generate more aqueous volatile components. Conversely, WT alone showed an optimal 46.4 wt% while WS-WT blend...
The increasing accumulation of oil palm empty fruit bunches (EFB) and polypropylene (PP) waste necessitates sustainable management solutions. This study investigates the co-pyrolysis EFB PP in a fixed-bed reactor at temperatures ranging from 400 to 600 °C, utilizing blending ratios 100:0, 75:25, 50:50, 25:75, 0:100. results revealed notable synergistic effects, particularly 75:25 EFB:PP ratio, which yielded 50.35% bio-oil, highest gas yield (28.95%), reduced biochar formation compared pure...
Fast pyrolysis in auger reactor gains attention for efficient bio-oil production. Due to the quick nature of process, precise temperature control using proportional-integral-derivative (PID) algorithm is paramount. This study harnesses various PID tuning approaches through modelling and experimental validation optimize continuous temperature. System identification was done investigate process dynamic with fit accuracy above 93% design a suitable control. Comparison experiment data shows...
Hydrogen is a promising renewable energy carrier and eco-friendly alternative to fossil fuels. Water-gas-shift reaction (WGSR) commonly used generate hydrogen from biomass feedstocks. Enriching content in synthesis gas (syngas) production can be made possible by applying the WGSR after gasification. achieve maximal carbon monoxide (CO) conversion using commercially patented CZA (Cu/ZnO/Al2O3) catalyst. This study proposed three in-lab self-synthesized catalysts evaluated compared with...
Pengolahan anaerob merupakan teknologi efektif yang murah untuk mengolah limbah cair kelapa sawit (POME) menjadi biogas dapat dijadikan bahan bakar atau listrik. Yield ditingkatkan dengan menerapkan teknik pretreatment POME sebelum menuju digester. Umumnya, ini adalah tahapan hidrolisis tahap pertama dari produksi biogas. Tujuan memecah padatan gumpalan komponen agar lebih mudah dicerna oleh bakteri. Studi berisi ulasan perbandingan keunggulan dan kelemahan beberapa metode terkini termasuk...

Abstract This study performed a comparative experimental analysis of vehicle performance, fueled with domestic gasoline and compressed natural gas (CNG). A passenger vehicle, 1.5 L, 4-cylinder engine was used as tool through road test, dyno test idling emission measurement. The 100% substitution method applied in all experiments. covered the distance Serpong-Bandung (Route I, 237 km) Bandung-Jakarta II, 142.4 km). In general, this revealed that performance parameters decreased by CNG usage,...
ABSTRACTPalm oil mill effluent (POME) produced from palm mills is classified as waste that can pollute the environment and needs severe treatment because it still contains high BOD COD. POME has potential to be further processed produce biogas products through anaerobic digestion process. Anaerobic process of production Palm Oil Mill Effluent a fermentation which quite long time. So necessary have pretreatment for preparation before being fed into biodigester reactor. It aimed at considering...

DME has characteristics similar to LPG so that the storage and handling are not different from LPG. could be used as a solvent can extract typical types of rubber/polymer material. The aims objectives this study determine effect DME/LPG (100/0, 80/20, 50/50, 30/70, 20/80) on stability mixture stove also observe several rubber materials/polymers accessories. reveals usage between 20/80 - 30/70 does require replacement any substitute materials but only requires minor modifications stove....
本研究では，インドネシア産の９種類の粘土粒子を流動媒体として実施したバイオマス水蒸気ガス化実験で得られた生成物のデータと使用した粘土の物性データを用いて，統計学的手法を用いて両者の因果関係を定量的に把握することが目的である。まず，因子分析により，実験で得られた５種類の物質収量を説明する２つの共通因子と，粘土の物性値（11種類）を構成する４つの共通因子が抽出された。その後，抽出された因子間の相関関係を重回帰分析により定量化し，物性データからガス化特性を予測する相関式を求めた。得られた相関式は，ガス化生成物の生成量を良好に予測することができた。得られた相関式と共通の因子を持つ物性値あるいは生成物データの相関係数から，特定の物性値が生成物データに及ぼす影響を定量的に評価した。その結果，ガスの収率向上には，比表面積の増加あるいはカリウム含有量の減少およびマグネシウムの減少が高い影響を持つ。一方で，タールの削減には酸量の増加および細孔径および細孔容積の増加が高い影響を持つことを明らかにした。
